Security code auditor is not an entry level position. Also known as an IT auditor, security auditor, secure code auditor, or source code auditor, security analyst, information security analyst, professionals lucky enough to find themselves in this role are accomplished and highly valued members of any cybersecurity team. Security code auditors must be versed in computer programming, systems and network security, penetration testing, cryptography, and software security protocols.
Only cybersecurity professionals with a broad-based background in the field will be effective as security code auditors. In many cases, source code audits are performed by independent outside consultants hired periodically to review an organization’s security status. Organizations with substantial cybersecurity budgets are much more likely to hire a full-time security code auditor than those with a small information security staff.

What is a security code auditor?
Code is the brains of all computer systems. If anything is wrong with
the brain, the entire system becomes vulnerable to problems, errors, and
especially incursion from outside sources wishing to create havoc, disrupt
operations, or steal secure information. Security code auditors are the brain
surgeons of computer systems. They analyze, diagnose and develop treatment plans for repairing any potentially problematic code vulnerabilities.
In order to evaluate the security of computer system code, source code
auditors must be familiar and knowledgeable of all aspects of hardware,
software and networks that comprise a complete system. The range of skills and experience required mean security code auditors are one of the most technically skilled members of any cybersecurity staff.
As the responsibility can be daunting for even the most experienced security auditors, analytical tools to assist taking on the job have been developed. There are numerous open-source and commercial source code analysis tools to help security code auditors uncover code vulnerabilities in hardware and software. These programs are also referred to as Static Application Security Testing (SAST) tools and can be invaluable aids.
Still, security code auditors must be able to sift through code line by line to uncover, determine the nature of, and develop a plan for the remedy of any problems.
Security code auditor skills and experience
In order to be able to thoroughly audit any organizations infosec status, a variety of knowledge and skills are required. Familiarity with penetration testing techniques, current cryptography protocols, network and systems security processes, software security vulnerabilities, and more must all be in the source code auditor’s bag of tricks. The list of required skills and experience in security code auditor job listings, therefore, are often numerous. Here is a sampling of some of the more common requirements.
- Knowledge of programming languages in C+, C++, Python, Ruby, Java, Perl, .NET
- Current familiarity with network and systems architecture, as well as security procedures and vulnerabilities
- Current familiarity with operating and applications software security techniques and vulnerabilities
- Knowledge of OWASP Top Ten vulnerabilities
- Familiarity with source code analysis tools, such as Bandit, Brakeman, .NET Security Guard, SonarQube, Application Inspector, Cast AIP and others
- Experience with penetration testing
- Familiarity with current encryption protocols and techniques
- Experience with database security
Soft skills often required by employers include the following:
- Highly analytical
- Strong written and oral communication skills
What do security code auditors do?
Information technology in any organization is a multi-faceted enterprise
consisting of hardware systems, communications networks, and software programs, and all of the protocols, permissions, procedures, and policies that determine the use of IT systems.
Security code auditors are responsible for ensuring the security of all
aspects of the IT systems they oversee. Fulfilling this responsibility requires
planning, executing and analyzing the results of exhaustive audits of every
nook and cranny.
This means being intimately familiar with programming codes used to
write the programs running the systems, as well as all security procedures in place within the organization and the laws affecting cybersecurity methodology. It also means being familiar with current techniques and procedures in use by hackers and having an up-to-date understanding of the most commonly exploited system vulnerabilities.
In short, security code auditors must know every minute detail of every aspect of the IT systems in use by the organization paying the professional’s salary. Source code auditors must plan and execute the most effective and most thorough audits possible to persistently determine the effectiveness of all security systems in place. It’s primarily a preemptive strategy to close vulnerabilities before they are taken advantage of by hackers.
But security code auditors must also perform or assist in the performance of forensic examinations of attacks on the system, whether the attempts are failed or successful. The answers found after such attacks must then be reported on and utilized to further tighten system security measures. In a world with constantly changing and advancing technologies and hacking techniques, the job of a security code auditor is never completely done.
